[cisco-voip] CFA/SNR fails with 503 Request Timeout at Proxy...

[Jonathan Charles]

CCM - H323 - CUBE - SIP TRUNK - Verizon SIP

We are seeing the following SIP errors on CFA/SNR calls:

SIP/2.0 503 Request Timeout At Proxy

Via: SIP/2.0/UDP 157.130.97.178:5060;branch=z9hG4bKACD87F86

From: "PLACE" <sip:ORIGINAL OUTSIDE CALLING
PARTY at scn10001.company.globalipcom.com>;tag=EB500DAC-20BF

To: <sip:SNR DESTINATION @scn10001.company.globalipcom.com
>;tag=aprqngfrt-9h004400000a6

Call-ID: 41B1BE63-80EF11E4-B597FDC8-B7F757A2 at 157.130.97.178

CSeq: 101 INVITE

Timestamp: 1418358981

Content-Length: 0



We have multiple office codes on our SIP trunk, all of them work except
this one; errors are consistent.


There is no DIVERSION field in any of the Invites.


Any ideas?
